Find each probability for one roll of a number cube:

12. P(4) 13. P(odd)

Answer:

m = -60

b = 300

y = -60x + 300

Step-by-step explanation:

(0,300) and (5,0)

m = y2 - y1/x2 - x1

m = 0 - 300/5 - 0

m = -300/5

m = -60/1

m = -60

y-intercept = b = 300

slope intercept form: y = mx + b

y = mx + b

y = -60x + 300

Answer:

m = -60

b = 300

y = -60x + 300

Step-by-step explanation:

(0,300) and (5,0)

m = y2 - y1/x2 - x1

m = 0 - 300/5 - 0

m = -300/5

m = -60/1

m = -60

y-intercept = b = 300

slope intercept form: y = mx + b

y = mx + b

y = -60x + 300

When he played outside how many object did he fetch in all is 12+r

An expression is combination of variables, numbers and operators.

Given that Spot fetched 12 sticks and some rocks

Let the rocks be denoted as r

We need to check when he played outside how many object did he fetch in all

The number of sticks are 12

The number of rocks are r

They are asking for total which means we have to sum the number of sticks and number of rocks

12+r

Hence, when he played outside how many object did he fetch in all is 12+r

Answer:

74.05

Step-by-step explanation:

1st step: plug -3.5 in for all values of x

y = 1/5(-3.5) + 7(-3.5)^2 - 11

2nd step: follow the order of operations by doing (-3.5)^2 to get 12.25

y = 1/5(-3.5) + 7(12.25) -11

3rd step: multiply 1/5 and -3.5 to get -0.7

y = -0.7 + 7(12.25) -11

4th step: multiply 7 and 12.25 to get 85.75

y = -0.7 + 85.75 - 11

Lastly, now that all operations are either addition or subtraction, work left to right

y = 85.05 - 11.00

y = 74.05

Let's look at an example.

-----------------------------------------

Problem:

At a high school play, tickets are sold at two different prices: student prices and parent prices. The student price is $2 while the parent prices is $3. On one night, 145 tickets were purchased and the total revenue was $335.

How many student tickets were purchased? How many parent tickets were purchased?

------------------------------------------

Solution:

Let x be the number of student tickets sold and y be the number of parent tickets sold.

We know that 145 people attended so x+y = 145 is the first equation we can set up. This equation is in standard form since standard form is Ax+By = C. Here we have A = 1, B = 1, C = 145.

The second equation we can form is 2x+3y = 335. This is also in standard form. This time we have A = 2, B = 3, C = 335.

The 2x is the amount of money made from just the students only. The 3y is from the parents only. The expression 2x+3y is the total from both groups. This total is set equal to 335 as this is the amount of money pulled in.

After forming both equations, we can write this system of equations

[tex]\begin{cases}x+y = 145\\2x+3y = 335\end{cases}[/tex]

To solve this system, we could isolate y in the first equation to get y = -x+145. Then plug this into the second equation to solve for x

2x+3y = 335

2x+3(-x+145) = 335

2x-3x+435 = 335

-x = 335-435

-x = -100

x = 100 .... number of student tickets bought

Use this to find y

y = -x+145

y = -100+145

y = 45 .... number of parent tickets bought

We can see that x+y = 100+45 = 145

And also 2x+3y = 2*100+3*45 = 200+135 = 335

These two facts help confirm we have the correct x,y values.

for 1 book=480

for 4 books= 480×4

=1920

Answer:

If one book costs 480, then four books will cost the quadruplee. To calculate it, we can multiply by 4 the price of one book:

480 * 4 = 1920

So we know it wouldd cost 1920 rp to buy four.

Answer:

x=2/3, y=0

Step-by-step explanation:

3x + 7y = 2,

6x - 5y = 4

Make the x coefficient the same in both equations.

3x + 7y = 2

(whole thing multiplied by 2)

6x + 14y = 4

Now subtract the equations to eliminate the x variable.

 6x + 14y = 4

-(6x - 5y   = 4)

        19y  = 0

           y = 0

Substitute 0 for y in one of the equations.

3x + 7(0) = 2

         3x = 2

           x = 2/3

well your equation has 2 equal signs in it but imma take a guess and say the first one is supposed to be a plus sign so

Answer:

x = 30

y = 7

Step-by-step explanation:

The triangle given is an equilateral triangle.

Equilateral Triangle

A triangle that has same length of all sides of triangle. They have same congruent internal angles as well.

So, If length of one side = 7

Length of other two sides will also be same i,e 7

Length of 2nd side = 7

Length of 3rd side = 7

Now, finding angles and value of x

The one angle is 2x, so the other two angles will be also 2x (because all angles of equilateral triangle are same)

We know that sum of all sides of angles of triagle = 180

We can write: [tex]2x+2x+2x=180[/tex]

Solving the equation to find x

[tex]2x+2x+2x=180\\6x=180\\x=180/6\\x=30[/tex]

So, x = 30

Since y is not given in picture, I think it is length of other sides i.e y = 7

Answer:

3450 miles

Step-by-step explanation:

Multiply the number 17.25 by 200 since the boat is traveling for 200 hours and each hour is 17.25 miles to get 3450 miles which is your answer.

Answer:

[tex]\boxed {\boxed {\sf 3,450 \ miles}}[/tex]

Step-by-step explanation:

Distance can be found by multiply the speed by the time.

[tex]d=st[/tex]

Where d is the distance, s is the speed, and t is the time.

1. Define Variables

The speed is 17.25 miles per hour and the time is 200 hours.

[tex]s= 17.25 \ mi/hr[/tex]

[tex]t= 200 \ hr[/tex]

2. Calculate Speed

Substitute the values into the formula.

[tex]d=17.25 \ mi/hr * 200 \ hr[/tex]

Multiply. The hours (hr) will cancel each other out and leave miles as the units.

[tex]d=17.25 \ mi *200\\[/tex]

[tex]d=3450 \ mi[/tex]

The voyage was 3,450 miles

Answer:

Solution is invalid

Step-by-step explanation:

Let the time when they will have the same water content be x hours

At x hours;

For the first tank, the content will be;

50 + 10x

For the second;

29 + 3x

Equating both, will give us x

29 + 3x = 50 + 10x

We will get x as a negative number here

Since number of hours can not be negative, the solution is invalid
